> Supporting HDFS NFS gateway with Federated HDFS

>
> Currently HDFS NFS gateway only supports HDFS as the underlying filesystem.
> Federated HDFS with ViewFS helps in improving the scalability of the name
> nodes. However NFS is not supported with ViewFS.
> With this change, ViewFS using HDFS as the underlying filesystem can be
> exported using NFS. ViewFS mount table will be used to determine the exports
> which needs to be supported.
> Some important points
> 1) This patch only supports HDFS as the underlying filesystem for ViewFS.
> 2) This patch add support to add more than one export point in the NFS gateway
> 3) Root filesystem of the ViewFS will not be mountable for NFS gateway with
> ViewFS,
> however this will not be the case for NFS gateway with HDFS
> 4) A filehandle now apart from the field will also contain an identifier to
> identify the name node, this will be used to map to correct name node for
> file operations.
> Please find the attached pdf document which helps in explaining the design
> and the solution.
